Technical field
The present invention relates to liquid, technical field of fluid delivery or Machining Technology field, particularly a kind of helical wheel structure of good seal performance.
Background technology
The material that spiral conveyor can be carried tradition to have screw conveyor shaft and band conveyor can not or not easily to carry, as graininess and granular material.Liquid and pasty material, semifluid and viscous material.The principle of work of conveyor screw is that material is passed and carries out by the helicallobe rotated, and material own wt and conveyor screw casing, to the friction drag of material, make material not rotate together with conveyor screw blade.
But existing helical blade structure, normally condition of equivalent thickness, limit by working accuracy, when helicallobe rotates in body, can not be formed with inboard wall of tube body and fit closely, cause the material carried to be gone here and there out between helicallobe and inboard wall of tube body, be easily stuck between helicallobe and inboard wall of tube body, as affected transmission efficiency when transmitting fluid or semifluid.
Summary of the invention
The deficiencies in the prior art in view of the above, the object of the present invention is to provide during a kind of transmission and can closely cooperate with inboard wall of tube body, the helical wheel structure of good sealing effect.
For achieving the above object and other relevant objects, the invention provides a kind of helical wheel structure, comprise center shaft, described center shaft is provided with at least a slice helicallobe, helicallobe described in every sheet at least forms a complete circle on center shaft, described helicallobe is justified in the projection that is projected as of center shaft axis, outer ledge and the described circle that projects of described helicallobe are tangent, and described helicallobe is reduced to outer rim by middle part gradually at the thickness of radial direction, and described helicallobe outer rim forms blade.
Adopt said structure, due to the circle of helicallobe projection formation rule, when for transmission field, owing to forming thinner blade in helicallobe outer rim, when transmitting, blade can be formed with inboard wall of tube body and coordinate closely, is all transferred out by material, and good sealing effect between inboard wall of tube body, thickness in the middle part of helicallobe ensures its holding capacity, is applicable to the transmission of fluid, semifluid etc.; This structure be used for field of machining time, can with drill bit with the use of, use as cutter as this helical wheel is arranged on drill bit afterbody, after piercing processing polished etc. is carried out to hole inwall, realize detailed manufacture, may be used for the boring on earth's surface equally, all can reach good effect.
Described helicallobe is two panels, and described in two panels, helicallobe alternately spirals on center shaft, and two panels helicallobe forms Central Symmetry relative to center shaft.Form Central Symmetry, when transmission or large hole machined, realize uniform force.
Described helicallobe Inner edge is connected with center shaft, and this helicallobe is reduced to Inner edge by middle part gradually at the thickness of radial direction, and the thickness of described Inner edge is greater than the thickness of outer rim, and described blade is tangent with projection circle.
This structure ensure that the intensity of helicallobe.
Curvature outside described helicallobe is greater than the curvature of inner side.Make helicallobe cross section be bending crescent, stressed and laser propagation effect is good, ensure outside blade with body or hole inwall tangent.
The helix angle of described helicallobe is 30 °-60 °.
The helix angle of described helicallobe is 45 °, is that transmission or processing effect all reach optimum 45 ° time.
Centered by described projection radius of a circle, the 4-5 of axle radius doubly.
Described center shaft at least one end is provided with connecting bore, for being connected with actuating unit or cutter etc.
Described center shaft and helicallobe one-body molded, one-body molded effective.
As mentioned above, the invention has the beneficial effects as follows: the circle of the projection formation rule of helicallobe, when for transmission field, owing to forming thinner blade in helicallobe outer rim, when transmitting, blade can be formed with inboard wall of tube body and coordinate closely, is all transferred out by material, and good sealing effect between inboard wall of tube body, thickness in the middle part of helicallobe ensures its intensity, is applicable to the transmission of fluid, semifluid etc.; This structure be used for field of machining time, can with drill bit with the use of, use as cutter as this helical wheel is arranged on drill bit afterbody, after piercing processing polished etc. is carried out to hole inwall, realize detailed manufacture, may be used for the boring on earth's surface equally, all can reach good effect.

Detailed description of the invention
By particular specific embodiment, embodiments of the present invention are described below, person skilled in the art scholar the content disclosed by this specification sheets can understand other advantages of the present invention and effect easily.
As shown in Figure 1 to Figure 3, the invention provides a kind of helical wheel structure, comprise center shaft 1, center shaft 1 is provided with two panels helicallobe 2, two panels helicallobe 2 alternately spirals on center shaft 1, and two panels helicallobe 2 forms Central Symmetry relative to center shaft 1.Form Central Symmetry, when transmission or large hole machined, realize uniform force, every sheet helicallobe 2 at least forms a complete circle on center shaft 1, and helicallobe 2 projects round 3 in being projected as of center shaft 1 axis, and the Inner edge 21 of helicallobe 2 is connected with center shaft 1, this helicallobe 2 is reduced by middle part 22 to Inner edge 21 and outer rim 23 gradually at the thickness of radial direction, and the thickness of Inner edge 21 is greater than the thickness of outer rim 23, blade is tangent with projection circle 3, and the outer rim 23 of helicallobe 2 forms blade.
Curvature outside helicallobe 2 is greater than the curvature of inner side.Helicallobe 2 cross section is made to be bending crescent, stressed good with laser propagation effect, ensure outside blade with body or hole inwall tangent, the helix angle of helicallobe 2 is 30 °-60 °, in this example, helix angle is preferably 45 °, be that transmission or processing effect all reach optimum 45 ° time, centered by the radius of projection circle 3, the 4-5 of axle 1 radius doubly.Center shaft 1 at least one end is provided with connecting bore 11, for being connected with actuating unit or cutter etc.
Center shaft 1 is one-body molded, one-body molded effective with helicallobe 2, and 3D printing technique can be adopted shaping.
Adopt said structure, because helicallobe 2 projects the circle of formation rule, when for transmission field, owing to forming thinner blade in helicallobe 2 outer rim 23, when transmitting, blade can be formed with inboard wall of tube body and coordinate closely, is all transferred out by material, and good sealing effect between inboard wall of tube body, in the middle part of helicallobe 2, the thickness of 22 ensures its holding capacity, is applicable to the transmission of fluid, semifluid etc., as cement mortar; When this structure is used for field of machining, can with drill bit with the use of, use as cutter as this helical wheel is arranged on drill bit afterbody, after piercing processing polished etc. is carried out to hole inwall, realize detailed manufacture, may be used for the boring on earth's surface equally, the complete circular hole of an inner wall smooth can be formed, as traditional drilling equipment, fitfull can not be formed at circular-hole internal-wall protruding.
